Home Made Brake Piston Wind Back Tool

Every time I change a set of brake pads, I wish I had one of those handy little tools to wind the piston back (rather than struggling with spanners and G Clamps). This was esepcially true yesterday, whilst changing pads on the Jag.

With a little time on my hands today (waiting for BT to try and sort out the mess they have made of my Broadband migration) I decided to have a go at making my own Piston retract tool.

I used an old brake disc (appropriate) for the flat sections (not sure what the techical term would be). Drilled and tapped a M10 hole for the treaded bar and then ran a drill, tap and length of M6 threaded bar through this for the handle.

Quite pleased with how it's turned out - can't wait to change another set of pads and see how it works.

Nice job what about some air hose over the "handles" to protect your hands from the threads?

Cheers Robostar - I was wondering how to make the handles more comfortable. Air hose will work nicely.

Cant remember what motor it was on now, but I too got fed up with g clamps, wedges of wood, pry bars etc.
But on this motor it was a single piston inboard and had a 'c' shaped cut out on the outboard side and it was solid would not move back even by cracking off the bleed screw.
So I went to my 'reserve' box of old, broken and not used very often tools and found a three leg puller whipped the legs off it and placed the spider in the c cut out and the screw in the base of the piston, cracked off the bleed screw again and wound the screw in and hey presto the piston went back easy.
Now though I have the Disco I will have to make or horror of horrors buy a set of windbacks.
